StreamMedia's Global Content Delivery Platform

StreamMedia is a video streaming service with 80 million subscribers across 45 countries. The platform stores 500 PB of video content, processes 10 billion daily API requests, and delivers 200 million streaming hours per day. The company operates 8 data centers globally but is experiencing latency issues for subscribers in Asia-Pacific and South America, with buffering complaints increasing 200% in those regions. The current architecture uses a single primary relational database for subscriber management, a distributed object storage system for video content, and a Redis-based caching layer for session management. During peak hours (8-11 PM local time across time zones), the primary database reaches 95% CPU utilization, causing subscription management errors and playback interruptions. The CTO wants to achieve 99.99% availability globally, reduce content delivery latency to under 50 milliseconds in all regions, support projected subscriber growth to 200 million within three years, and maintain data consistency for billing and subscription management across all regions.
